Title: Improvements relating to fuel elements for nuclear reactors
Inventor: PAGET JOHN ARTHUR
IPC: G21C15/04
Filed: 1958-09-02
Abstract: 880,571. Nuclear fuel elements. BOYD Ltd., WINNETT. July 13, 1959 [Sept. 2, 1958], No. 28179/58. Class 39(4) A nuclear fuel element for use in a horizontal position comprises a closed tubular casing of moderating material containing wafers of fuel material. The wafers do not completely fill the cross-section of the casing, but a large area of contact is obtained by making at least part of the surface of each wafer to fit exactly into the lower part of the internal surface of the casing. Thus, Fig. 5 shows a casing 11 of internal radius R, containing a wafer 10 whose periphery consists of three equal arcs all of radius R but having different centres so that every diameter of the wafer is less than 2R. The outer surface of the casing may be shaped in the same way for close fit in a surrounding tube. Alternatively, the wafer could be circular and the interior of the casing made up from circular arcs of the same radius. Fig. 8 shows the principle applied to triangular wafers 24 in triangular casings, the whole lying in finned triangular tubes 25 dispersed among moderator blocks 26, with undulating, generally vertical passages 27 for a gaseous coolant such as He. The moderator may be graphite, the fuel oxides, carbides or cermets of U, TR, or Pu. The fuel wafers may have graphite centres or may vary in size or in other ways, and Fig. 1 shows a casing with grooves 16 whose arrangement indicates the contents of the casing. The end plugs are dished dished to reduce bending stresses.

Title: Improvements in or relating to apparatus for simultaneously surfacing both surfaces of a moving ribbon of glass
IPC: B24B7/24
Filed: 1952-11-17
Abstract: 727,692. Surfacing glass. PILKINGTON BROS., Ltd., BARNES, P. C., and COOK, T. S. Nov. 16, 1953 [Nov. 17, 1952], No. 29025/52. Class 60.  Apparatus for simultaneously surfacing both surfaces of a moving ribbon of glass 1, Fig. 1, comprises co-operating pairs of tools 5 the axes 3 of which are disposed in vertical planes 4 lying obliquely to the path of the ribbon, and driving means operating against each face of the ribbon and arranged between one pair of tools and an adjacent pair, each driving means being constituted by a set of short rollers 8 carried by a beam 9 disposed obliquely to the path of the ribbon whereby the rollers are arranged in echelon with their axes at rightangles to the direction of ribbon movement. The rollers 8 are arranged in pairs on a common axle 19, Fig. 3, each of which is journalled in a bracket 17 and driven by a worm gear 20 and bevel gears 16, 23 from a shaft 15, the gears 16 being axially adjustable on the shaft 15. The shafts 15 in each pair of beams 9 are driven through bevel gears 13, 14, Fig. 2, from a common vertical shaft 12 rotated by a motor 11. To enable the beams to be vertically adjusted, the gears 13 are slidably splined to the shaft 12 and the ends of the beams are mounted on guide bars and engaged by screw-threaded rods 45, 51 and 46, 52. The rods 45, 51 control the lower beam and are rotated by bevel gears and a shaft 38, Fig. 8, geared to a spindle 31, Fig. 6, carrying a hand wheel 26 while the rods 46, 52 control the upper beam and are rotated in a similar manner by a hand wheel 27 on a sleeve 30 geared to a shaft 39. The connections between the rods and the beams each include a slidably keyed nut which moves in relation to the rod once the rollers have engaged the glass and hence prevents the application of excessive pressure. Each shaft 19 may alternatively be driven by a separate synchronous electric motor mounted within the beam 9. Fig. 12 shows an alternative arrangement in which the rollers 8 are driven in series through gears 60 and idler gears 61 which cause all the rollers to rotate in the same direction. In both arrangements, the rollers are rubber covered and some of the sets may be undriven so that they act only as a support for the glass. The tools are driven by a motor 7 and may be grinders or polishers.

Title: Apparatus for controlling television signals
IPC: H04N5/272
Filed: 1959-11-05
Abstract: 886,087. Television. FERNSEH G.m.b.H Nov. 5, 1959 [Nov. 5, 1958], No. 29064/61. Divided out of 886,086. Class 40(3). Relates to apparatus, Fig. 2, for controlling television signals comprising means for applying television signals from each of two television scanners 1, 2 to a combining circuit 5 by way of gate circuits 3, 4 which are opened alternately by the action of a keying signal produced by scanning a master pattern 7 by means of a third television scanner 8. The signal from the combining circuit represents a composite image in which the scene viewed by the first of two scanners is replaced by the scene viewed by the second of the two scanners over an area determined by the master pattern scanned by the third scanner. In accordance with the invention the phase of the keying signal relative to the gated televisionsignals is arranged to -be varied, in order to permit the position of the area to be adjusted by applying synchronising impulses from source 35 to trigger the scans in the third scanner via adjustable delay means 36. In one arrangement, Fig. 3, the original synchronizing signals are applied to generate a sawtooth wave -M which is limited at an adjustable level 37 to generate a square wave N. Differentiation as at O and selection of the positive-going pulses P enables delayed blanking and synchronizing pulses Q and R to be developed. The amount of delay is varied by adjustment of limiting level 37. Similar arrangements are provided for line and frame synchronization. The two delay adjustments are preferably controlled by a common "joy-stick" type of control. An impulse generator 22, mixer 23 and limiter stage 25 are provided to introduce reference level pulses into the keying signal during the blanking intervals which function to set the trigger level of a phase-splitting stage 10 which provides oppositely phased versions of the keying signal for control of the gate 'circuits 3, 4. The size of the inlay area may be varied by controlling the amplitudes of the scan signals in scanner 8. As an alternative to varying the area size by variation of raster size, the size of the image of the master patternpresented to the third scanner may be varied either by varying the distance of the pattern from the scanner or by use of a lens system of variable magnification. Reference is made to the rotation of the area, this being brought about either by rotating the pattern in a plane perpendicular to the optical axis of the: third scanner, or by the use in the scanner of a pick-up tube including an image section in which the electron image may be rotated. Preferably a number of different master patterns may be provided which may be carried by suitable members to permit their introduction into the optical path of the third scanner when required.
